pulverized-coal combustion

Pulverized-coal combustion is a widely used technology in large power stations for generating electricity. In this method, coal is ground into a fine powder, allowing for faster and more efficient combustion reactions due to increased surface area. This process enables the burning of various types of coal with high efficiency, producing steam to power turbines.

However, this technology has drawbacks, including the costs associated with drying and grinding coal, potential fouling of heat-transfer surfaces, and the need for expensive equipment to collect fine particles. Additionally, coal combustion releases significant amounts of carbon dioxide, a major contributor to global warming, and other pollutants like sulfur and nitrogen oxides, which contribute to acid rain.12
